Determined to break the "bubble" surrounding the US presidency, tech-savvy Barack Obama said he was "negotiating" with the Secret Service and others whether he could retain his Blackberry after moving to the White House.

Obama, who will succeed incumbent George W Bush as the 44th US President on January 20, said he was concerned that the isolated life of a president would limit his access to information from outside the bubble of the White House.

Throughout the gruelling presidential campaign, Obama was often seen communicating via his Blackberry mobile phone, a convenience he may legally have to forgo.

For national security purposes, a president has limited access to electronic correspondences for fear of hacking. Additionally, presidential communications are strictly monitored and archived for historical purposes.

"One of the things that I'm going to have to work through is how to break through the isolation -- the bubble that exists around the president.

"I'm in the process of negotiating with the Secret Service, with lawyers, with White House staff ... to figure out how can I get information from outside of the 10 or 12 people who surround my office in the White House," Obama said in an interview to ABC News.

Last week, the 'New York Times' had reported that Obama, apparently addicted to the Blackberry, may have to give up his high-tech instrument.

Quoting Obama's aides, the report had said he hopes to have a laptop computer on his desk in the Oval Office, making him the first American president to do so.
